CHICAGO — At a recent wedding reception in Chicago, guests gathered to toast the newlyweds at the bar. Glasses were lined up in front of them, but no alcohol was poured. Instead, marijuana vapor was pumped into the upside-down glasses, which were then lifted and inhaled in unison. “A lot of people were surprised,” bride Aja Heinlein said. “They didn’t even know that was something they could do.” In the new world of cannabis, consumption at private events such as weddings, holiday parties and corporate events is becoming more common.
